J. Sluijter et al., EXPERIMENTAL VALIDATION OF PO UTD APPLIED TO FRESNEL-ZONE PLATE ANTENNAS, Microwave and optical technology letters, 9(2), 1995, pp. 111-113
The electromagnetic modeling of the Fresnel-zone plate antenna (FZPA)
by means of physical optics (PO) and the uniform theory of diffraction
(UTD) is experimentally verified. Near-field measurements on basic co
nfigurations of the FZPA (i.e., a slit and two rings in a metallic pla
te) at 50 GHz and far-field measurements on a complete FZPA at 11.5 GH
z show good correspondence with computer simulations based on UTD and
